Different function can be executed with different order and/or be mutually performed simultaneously.In addition, if desired, one or more described
Function can be optional or can be combined.In this way, the rule that should be to be considered merely as of the invention, religion is described below
It leads the explanation with embodiment and is not intended as its limitation.
Some embodiments of the present invention can be applied to LTE-A, including 3GPP LTE-A Rel-12, Rel-13 and thereafter
Continuous, they solve the LTE-A support of the D2D discovery for network-control.3GPP has begun to referred to as close service
(ProSe) the potential service and requirement for D2D communication is studied.One of target of the research is to look at use-case and marks
Know the hair for the carrier network control between the equipment being close under contiguous network control and/or the 3GPP network coverage
Now with the latent demand of communication.This may be for this purpose: business/social uses, network unloading, public safety and/or
The integration of current infrastructure service with ensure include the user experience of accessibility and mobile aspect consistency.
Newest RAN plenary session result includes certain requirements of the priority criteria project in relation to LTE ProSe D2D communication.
The result of RAN 1#74 includes for being used for unicast and the PHY broadcast that multicasts, and baseline is that do not have PHY closed loop feedback, i.e.,
Hybrid automatic repeat-request (HARQ), power control etc..For higher, unicast multicasts and broadcasts needs and supported.
These different higher level services are handled by the broadcast in PHY layer.Baseline be there is no HARQ in PHY, but in L2 may
There is automatic repeat request (ARQ) support.Therefore, it is necessary to how facilitate on such L1 based on broadcast the D2D of robust logical
Believe the aggregate concept of (unicast multicasts and broadcasts).
Selected equipment is being coordinated and may control in the possibility D2D communication between cluster member just playing special work
The use of the D2D cluster of Star topology is a kind of method for supporting ProSe D2D to communicate.D2D cluster can be how
It is that cluster member is coordinated and distributes physical resource to be directed to that the example for providing the D2D communication based on broadcast, which includes cluster head end (CH),
Their requested (multiple) individual consumers or (multiple) groups of users are sent in cluster.
One of challenge in relation to physical source distributing is, it is assumed that the physical resource pool for D2D all in cluster communication
It is limited, CH how to be coordinated the active individuals user to ensure as cluster member and effective between groups of users and
Fair physical resource is shared.Biggish D2D communication group with more business demand and transmitter may need smaller
The more physical resources of group.Since these factors may be dynamic, thus can be currently formed by groups of users with
And their transmission/reception activity is monitored and can be advantageous for effective physical source distributing.
Public safety (PS) use-case situation is the group communication of task key, such as can have following basic operation:
1. should not have more than 6-8 D2D ProSe group communication group in the site of the accident using parallel online operation；2. utilizing
Concurrent online operation should not have and be assigned to each D2D ProSe group communication group more than more than 12-16 user,
But group size can extend to 50-70 user to accommodate searching rescue team, and can be reduced to 2 with shape
At " personal call " of the authorization between two members of given group；And 3. operation for D2D ProSe group communication
Geographic area can be up to the radius of 1.5 miles of each site of the accident.
Therefore, in the site of the accident (interested coverage or position), there may be multiple groups of users, and all
It requires to be communicated with effective and reliable way.Therefore each group should have in a manner of semi-durable for its institute
Some physical channel resources of distribution at least ensuring that basic communication requirement, it is contemplated that different user, groups of users,
The attribute of application and service, in terms of sharing shared physical resource pool, all groups can be again public with First Come First Served
Flat mode is operated.Therefore, it is main problem that effective and fair physical resource between active user group is shared, and
It is not congestion or overload prevention.As an example it is supposed that for interested D2D group communication overall physical channel resource pool by
10 channels are formed.Occur the first groups of users (for example, fireman) at the scene for example can have 20 members and
It is allowed using 5 channels.This is acceptable, until the second group (for example, police), third group (for example, medical treatment) with
And until more users group reaches scene.Each of these groups may have at least one letter distributed for it
Road, and can have according to the number of members and its communication requirement in each group the channel of some more distribution.?
Under some cases, the first groups of users may not be allowed to require more physical channel resources, or even must at least exist
One or two channel is abandoned in certain time for other groups.
Therefore certain embodiments of the present invention solves the physical source distributing for the D2D group communication based on broadcast
Fairness problem, the above-mentioned D2D group communication such as group communication based on 1:M broadcast based on D2D cluster.Some implementation official holidays
If following system, wherein when transmission (Tx) user equipment (UE) member makes requests, allocated channel, above-mentioned UE member are public by CH
Open its Tx UE ID and expected reception (multiple) (Rx) UE ID or (multiple) group ID.Therefore, CH actually sufficiently knows
Distribute to individual UE and the physical resource of its groups of users.Therefore, in the case where not needing to carry out complex control, CH can
Physical source distributing (RA) between UE and its individual consumer group is coordinated in a manner of fair and is effective.Therefore, certain
A little embodiments provide a method comprising reply (multiple) " greediness " user or groups of users are so that it is guaranteed that fair and effective
RA mechanism.
Fig. 1 illustrates the simplification examples of the communication system 100 according to one embodiment.In this example, system 100 includes
One eNB-eNB1 and six UE (UE1-UE6).However, as those skilled in the art will readily appreciate that, system 100
It may include any number of eNB and/or UE.In this example, eNB1 can in its coverage for example including
The UE of UE1-UE6 is serviced.Therefore, in some embodiments, UE1-UE6 can be by cellular via eNB1
It is serviced.In addition, in this example, UE1, UE2 and UE3 can carry out D2D communication, and UE4, UE5 and UE6 can be carried out
D2D communication.Therefore in one embodiment, UE1, UE2 and UE3 can form a groups of users, and UE4, UE5 and UE6 are then
Another groups of users can be formed.Certainly, as discussed above, may include in each groups of users other UE and
Number of users in groups of users is not necessarily limited to the example.According to some embodiments, UE1, UE2, UE3, UE4, UE5
And/or any one of UE6 can be used as cluster head end (CH).Other UE for not serving as CH are then considered collection
Group members.
As an example, the UE in Fig. 1 can form cluster, wherein such as UE5 serve as CH and remaining UE then be collection
Group members.Both communication user groups (that is, UE1-UE3 and UE4-UE6) may be under coordination/control of CH.However, CH
Control signaling between UE member is not described in Fig. 1.Fig. 1 illustrates the situations in the network coverage.The network coverage
D2D cluster and group communication in outer situation or more generally autonomous D2D, which are communicated, to be supported.
The embodiment of the present invention makes CH cope with its (multiple) " greediness " member and/or groups of users so that it is guaranteed that public affairs
Flat and effective RA.In one embodiment, CH can consider user, groups of users, the priority of application and service and want
The transmission between local activity user (for example, member of some groups of users) and its groups of users/connect is monitored in the case where asking
Folding movable and physical resource use.
According to one embodiment, it is based on the monitoring, CH can issue taboo in the predefined D2D broadcast control channel of CH
User only from active user group to the physical channel resources for distributing to the active user group be extended into one
Walk the explicit instruction of request.The active user group can be identified in the explicit instruction.In embodiment, to extend
Physical channel resources further request forbid until to have effectively or before other notice within certain time
Effect, is counted at the time of transmission from explicit instruction or from the offset with it.In alternative embodiments, which can
It will be rejected within certain time as indicated with the such request of instruction or be all rejected before other notice.
In another embodiment, CH can issue CH to some active user group and be intended to since at the time of indicated
The alert message of the physical channel resources distributed of (free up) (or withdrawal) certain quantity, the activity are vacated from the group
Groups of users identifies in the alert message.For example, CH can be by selected by those since at the time of indicated
Physical channel resources be designated as free physical resource or in the broadcast control information of update by those from potential user group
It removes in the related indicated channel occupancy information of group and selects to withdraw some distributed from target user group perspectively
Physical channel resources.It should be noted that since being designated as being expected into the alert message at the time of sending alert message
At the time of moment, the CH can monitor the possible channel release request of the active user from target user group and according to
Those requests are to select the physical channel resources to be withdrawn.The alert message can implicitly or explicitly include begging for as before
The instruction of the request for forbidding or refusing the extension physical channel resources from identified group of opinion.In one embodiment, should
Alert it is effective always, until the request for forbidding or refusing the extension physical channel resources from identified group instruction when
Between section it is expired, perhaps until physical channel resources having been adjusted or as indicated in the warning until any one
Occur earliest.
In yet another embodiment, CH can issue explicit or implicit instruction, wherein the implicit instruction can together with
On the following examples that are discussed implicitly realize that wherein certain distributed physical channel resources of groups of users are present together
Can with for the groups of users certain predefined groups in Channel Sharing operation mode (for example, some competition-based
Access or the access based on token) and used.In implicit instruction option, all institute's allotments reason resource of groups of users is all
It can be used with Channel Sharing operation mode in certain predefined group (for example, some by the member in the groups of users
Access competition-based or the access based on token).
In some embodiments, CH can monitor that (multiple) specific to selected active user or groups of users divide
It the activity for the channel matched and is withdrawn based on the result monitored.For example, if CH is received by corresponding transmitter
L continuous false point sent on distributed channel when no other data will be sent every the predefined interval T
Group, then CH can vacate the channel.The selection can be based on (between potential greediness user or groups of users) physical resource
Shared fairness or the report based on the reception user from certain distributed physical channel resources.The monitoring of CH
(for example, L and T parameter) and judgement it is also conceivable to such as to include CH and including all relevant user equipments pre-configuration with/
Or the service priority as indicated by cluster member, group priorities, User Priority etc. and any of them may combinations.
According to one embodiment, cluster member UE can be configured as monitoring in the D2D broadcast control channel of CH from CH
Send most newly control information and correspondingly react.Therefore, as described above as indicated by CH or warning use
The behavior and movement of cluster member UE in the group of family corresponds to CH control signaling discussed above.In addition, in embodiment,
Cluster member UE in (multiple) groups of users as discussed above as indicated by CH or other than warning, which can also be monitored, to be referred to
Show or alert message, such as about when attempting (or retrying) request physical resource and make to know or the judgement of intelligence.At certain
Having in a little embodiments, in cluster (unrelated groups of users) can be by for the UE member of its dedicated physical channel resource distributed
It is configured to monitoring and it did not had data to request to release perspectively in the case where transmission within the period being specifically pre-configured
Distributed physical channel resources are put, the above-mentioned period can be specific to service priority, group priorities, User Priority etc.
And any of them may combination.
Fig. 2 illustrates using for handling (multiple) " greediness " in the D2D communication based on broadcast according to one embodiment
The example of the flow chart of the method for family or groups of users.In one embodiment, this method can be by the network entity of such as CH
To execute.This method includes depositing for (multiple) the different active user groups for monitoring shared local/physical channel resources 200
?.The monitoring for being somebody's turn to do (multiple) groups of users may include surveillance operation group member, transmission activity, user and its service or more
Text holds time interval including the physical channel resources distributed and channel, with active user group, active group member's kimonos
Be engaged in related priority, etc..
This method may further include Fairshare 210 for example based on pre-configuration rule (for example, being monitored
The threshold value and/or function of output) determine or calculate local/physical channel of each of (multiple) groups of users groups of users
The current share of resource.This method then may include determining when be somebody's turn to do one or more of (multiple) groups of users 220
With the maximum fair share for its physical channel resources distributed.If it is determined that there is no groups of users to be assigned to physics
Its maximum fair share of resource, then this method can return to 200.If it is determined that there is groups of users to be assigned to physical resource
Its maximum fair share, then this method may include determining whether remaining physical resource is enough to support (multiple) user group 230
Each of group.
If it is determined that remaining physical resource is sufficient, then this method may include issuing instruction 240, and the instruction is specific to quilt
It is identified as the groups of users of the lion's share with the physical resource for its distribution.As the above mentioned, in one embodiment
In, the instruction can be forbid in the predefined D2D broadcast control channel of CH the user from active user group to distribution
The explicit instruction further requested being extended to the physical channel resources of the active user group.
In one embodiment, the maximum fair share of physical resource pool can be the threshold value of pre-configuration, such as current total
In body physical channel resources or particular percentile that at least one groups of users can be assigned, and it is how many different from existing
The business demand of active user's groups or users group is unrelated.In another embodiment, fair part of the maximum of physical resource pool
Volume be also possible to according to the opposite physics resource-sharing between different user group without shut down (on-the-fly) update
Amount, above-mentioned groups of users can be it is existing and can for robust operation expected new groups of users.As non-limit
Property example processed, if only single current active user group, which, which can be allowed to use, is for example up to 80%
Physical channel resources.As another example, if there is the Liang Ge active user group of progress voice group call, wherein one
A have 20 members and another has 10 members, then first can be allowed to use up to 50% physical channel money
Source and another then up to 25%.Remaining 20% can be preserved for enabling (multiple) new groups of users, which ensure that
Robust that PC is used and reliable operation.
Return to Fig. 2, if it is determined that remaining physical resource is simultaneously inadequate, then this method may include giving a warning 250, should
Alert the groups of users specific to the lion's share for being identified as to have for its physical resource distributed.As mentioned above
, which can be for the groups of users identified, CH and is intended to for example since at the time of indicated from group sky
The alert message of (or withdrawal) certain amount of distributed physical channel resources out.
Due to the requirement of the height reliability used for PS, dash forward for the distributed physical channel resources of groups of users
So variation may cause loss of data or send delay, or even results in and influence ongoing service or its service quality
(QoS) service disruption.Therefore, following alert message as described herein is quite preferred, the police for PS service
It accuses message and can permit associated user group and (groups of users that is warned and need this to be warned in a manner of Fairshare
Those of some physical resources of groups of users groups of users) there is the sufficient time to be prepared or adjust.The warning can be with
Opposite or absolutely instruction comprising the expected physical resource quantity being retracted compared with the quantity distributed when alerting.At another
In embodiment, which may include the instruction of the physical resource of expected maximum (and/or minimum) quantity being retracted.The warning
Further using the possible revocation currently alerted or it can deactivate and be enhanced before at the time of indicated its comes into force.
For example, if CH before the indicated moment enough in advance (this can use false alarm timer to implement) determination sent out
